Polymer has been successfully used to enhance crude oil recovery at high water cut stage. However, the application of polymer flooding is limited by heterogeneity reservoir. In this work, role in heterogeneous reservoir was explored nuclear magnetic resonance (NMR) spectroscopy. Parallel core displacement experiments were carried out study formation. The results showed that area related permeab...

wild plant germplasm possesses useful adaptive strategies. wild plant species, for example, are resistant to biotic and abiotic stress and can be used for reforestation, agriculture, and horticulture. we surveyed the potential of wild pear to resist flooding. we looked at survival, growth, biomass, and several physiological variables. the rootstocks of wild pear are candidates for planting in o...

The polymer recovery efficiency of cationic polyacrylamide (PAM) has been evaluated for use as flooding in the Basra oil reservoir Initially, rheological, physical and petro were studied. Additionally, core experiment tested to see how well PAM solutions can be recovered. comparative study between experimental numerical solution accomplished terms rheological properties , relative permeability ...

Abstract Chemical enhanced oil recovery (EOR) methods are shown to sweep the residual by altering physical properties of fluids after waterflooding improve recovery. This work presents an experimental study on surfactant/polymer injection for EOR in sandstone reservoirs. Interfacial tension measurements, emulsification and rheology tests performed select best candidates from thirteen commercial...
